Recently, the annual production of 100,000 tons of 1,4-butanediol project carried out by Yichuan County Industrial Park Investment, Development and Construction Co., Ltd. has been registered. Project Name: Yichuan County Industrial Park Investment, Development and Construction Co., Ltd.’s 100,000-ton-per-year 1,4-butanediol production projectLaunch Date: October 28, 2025
Region: Shaanxi
Project Owner: Yichuan County Industrial Park Investment, Development and Construction Co., Ltd.
Total Investment: 1.9 billion yuan
Construction Location: An area of 100 mu north of the Niujia Dian area in Yan’an City, Shaanxi Province
Project Details: The production capacity of the BDO facility in this project is set at 100,000 tons per year; in addition, there will be a 40,000-ton-per-year facility for producing acetylene from natural gas, a 100,000-ton-per-year facility for producing methanol using the acetylene off-gas recovery method, and a 200,000-ton-per-year facility for producing formalin (37%). The annual operating time is 8,000 hours in each case. BDO mainly supplies downstream plants for PBS series polyesters, PTMEG, etc. Excess acetylene feedstock can be supplied to the alkyne alcohol plant, while excess methanol is sold externally. The project involves the construction of a facility with an annual production capacity of 100,000 tons of BDO (including units for acetylene, methanol, and formaldehyde), with a total investment of 1.9 billion yuan.
